What I claim is: 1. A hot gas valve 'for alined ends of coaxialconduitsdening a transverse slot comprising a pair of annular membersprovided With opposed annular seats, means for flexibly securing saidmembers to the respective conduit ends, a pair Y of housngssupported by,and diametrically olisposed relatively to, -said annular members and ucontacting at both ends said annular members Vconduit ends, spacedopposed annular exible diaphragms secured to said supports and `extendedinwardly of the latter, annular opposed anglessecured to said diaphragmsvand having longitudinally disposed legs and outwardly extendedtransverse legs provided with opposed spaced seats, each of said angleshaving a pair of diametrically opposed openings through the longitudinalleg thereof, a pair of housings diametrically arranged relatively tovsaid angles and extended at their ends through the openings in therespective angles, said housings each contacting their respective anglesclosely upon opposed longitudinally spaced sides of the housings andactuating means for moving said housings in opposite directions saidactuating means exerting a rectilinear thrust upon said housings.

3. A hot gas valve comprising an annular member formed with a seat andhaving exible supporting means, a transverse housing fixed at its endsto said member, a transverse actuating lever contained Within thehousing and secured to the latter centrally of the ends of the housing,and means for moving the lever` to exert a rectilinear thrust upon thehousing.

4. The combination With a pair of longitudinally-spaced aligned conduitends defining an open transverse slot therebetween; a pair of transverseannular members flexibly supported from the respective conduit ends andprovided with longitudinally-opposed annular seats, a plate between theseats, means for moving the plate transversely, and means for moving theannular members longitudinally relatively to each other, said movingmeans including a pair of laterally closed and open-ended structuresdisposed in the open slot and respectively connected to the annularmembers, thrust means disposed within the rel spective structures,A andmeans for causing said conduits defining a transverse slot comprising avpair of annular members provided With opposed annular seats, annularflexible supporting means secured to each of said members and extendedoutwardly therefrom,` diametrically arranged housings xed at their endsto said members, L

respectively, transverse actuating levers secured Within and to thehousings, respectively, and means for moving the levers.
